Samsung 55" S90F OLED 4K TV vs LG B3 Series OLED 4K TV

Both are 55-inch 4K OLEDs at 120 Hz, so the picture fundamentals are close: perfect blacks, wide viewing angles, and smooth motion. The Samsung S90F adds an anti-glare coating, four HDMI ports, and a slimmer, lighter build, which suits bright rooms and multi-device setups. The LG B3 runs webOS with Siri support and comes in more sizes, but it is heavier, has fewer HDMI inputs, and its B-series panel is LG's entry OLED tier. Owners of both rate them 4.6 out of 5; pick the Samsung for a brighter room and more ports, the LG if you want webOS or a larger size.

• Choose the Samsung S90F if you watch in a bright room, need four HDMI inputs, or want the lighter, thinner set.
• Choose the LG B3 if you prefer webOS, use Siri, or want the option of a 65- or 77-inch screen.
